The main causes include infection with Helicobacter pylori, poor diet (high in salty and processed foods), smoking, obesity, and a family history of gastric cancer. Genetics and chronic stomach conditions like gastritis can also increase risk.

Early symptoms may include persistent indigestion, unexplained weight loss, nausea, a feeling of fullness after eating small amounts, and abdominal discomfort. These signs can be easily mistaken for other digestive issues.

Currently, there is no standard screening test for the general population. However, individuals at high risk, such as those with a family history or chronic infections, may benefit from regular screenings like endoscopy.

Preventing stomach cancer involves maintaining a healthy diet, avoiding smoking, limiting alcohol intake, staying active, and managing weight. Regular screenings for those at high risk also play an important role.

Treatment depends on the cancer’s stage and may include surgery to remove part or all of the stomach, chemotherapy, radiation therapy, targeted therapy, or immunotherapy. A combination of these may be used for better results.

Maintaining a balanced diet rich in fruits, vegetables, and whole grains, staying physically active, and quitting smoking can help improve treatment outcomes and overall well-being. Limiting alcohol consumption is also recommended.

Stomach cancer can be treated effectively if caught early. However, the prognosis depends on the cancer’s stage at diagnosis. Advanced-stage cancer may be more difficult to treat, but palliative care can improve quality of life for patients.
